Abstract:
The motivation for constructing a thin-shell wormhole from a (2+1)-dimensional rotating black hole arises from the desire to study the effects of a nonminimally coupled scalar field in this particular spacetime. By investigating the behavior of such a field in the presence of rotation, we can gain insights into the interplay between gravity and scalar fields in lower-dimensional systems. Additionally, this construction allows us to explore potential connections between black hole physics and exotic phenomena like traversable wormholes. The radial perturbation around the equilibrium throat radius is considered to explore the stable configuration for specific values of physical parameters. Then, the equations of state, specifically the phantom-like and generalized Chaplygin gas model for exotic matter is used to conduct an extensive investigation into the stability of the counter-rotating thin-shell wormholes. Our results show that the presence of a scalar field enhances the stability of the counter-rotating thin-shell wormholes.

从(21)维旋转黑洞构造薄壳虫洞的动机源于研究该特定时空中非最小耦合标量场的影响的愿望。通过研究这种场在存在旋转的情况下的行为,我们可以深入了解低维系统中重力场和标量场之间的相互作用。此外,这种构造使我们能够探索黑洞物理学与可穿越虫洞等奇异现象之间的潜在联系。考虑围绕平衡喉部半径的径向扰动,以探索物理参数特定值的稳定配置。然后,状态方程,特别是用于外来物质的类幻影和广义Chaplygin气体模型,用于对反向旋转的薄壳虫孔的稳定性进行广泛研究。我们的结果表明,标量场的存在增强了反向旋转的薄壳虫洞的稳定性。
